ABOUT OUR SAMPLES ABOUT OUR SAMPLES

Routine Samples Ready to Analyze AOAC’s proficiency testing samples arrive at the laboratory ready to analyze like routine samples. AOAC’s samples go through rigorous homogeneity testing before the samples are shipped. Stability testing is completed at the round’s end. Other companies that offer proficiency testing programs have samples that have to be prepared and mixed prior to analysis; this can present an opportunity for error and also takes additional time and resources. Samples Used for Evaluation The AOAC Proficiency Testing Program has procedures in place to ensure that the result data the participating laboratories’ receive meets the requirements that were determined by an advisory task force consisting of international experts. If a sample fails to meet the requirements then that sample is flagged for review and may not be used for evaluation.
